MACHINE FOR PLANING AND JOINTING BARREL-STAVES.

SPECIFICATION formng part of Letters Patents No. 439,089, dated October 28, 1890.

Application filed April 17, 1889. Serial No. &07,624. (No model.) Patented in Germany February 12, 1889, No. 49,812, and in England March 25,1889,No.5,121l

To all whom it may concern:

Be it known that I, JOHANN ANTHON, machine-maker, residing at Flensburg, in the Province of Schleswig-Holstein, Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Machines for Planing and Jointing Barrel -Staves, (patented in Germany February 12, 1889, No( 49,812, and in England March 25, 1889, No. 5,121,) ofwhich the following is a specification.

The object of my invention is to provide a machine for planing on both sides or j ointing barrel-staves of 'an irregular, Winding, or crooked shape, as they are rived from the block, thus obviating the necessity of having an extra machine for straightenin g said staves before they are operated upon.

With this object in Viewmy invention consists in the combination, with the planin g-cutters, of a free or yielding holder and carrier adapted to engage the stave and movable in directions transverse to the line' of feed or approach to the cutters to accomnodate the requirements of the stave.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect.

In said drawings, Figure l is a side View, partly in section, of a machine embodying my invention, having therein a stave in position for being planed. Fig. 1 is a sectional View of the guide-bars for the tappets of the end- Fig. 2 is a View of another machine also ernbodying my invention and having a single downhold or presser for the stave, and provided with jointing-cutters and with a slightly-modified form of carrier and carrier-guide. Fig. 3 is a sectional view on line 3 3, Fig. .4. Fig. 4 is a modification of the Construction shown in Fig. 2, conprsing a reciprocating carrier. Fig. 5 is a sectional View looking from the right of Fig. 4.

Referring to the said drawings, 'iz' represent rotary cutters or planing-knives, which may be arranged for Operating upon the top and bottom of the stave, as in Fig. 1, or upon cutters are mounted upon a suitable frane and actuated by any desired or usual mechanism.

The free or yielding holder and carrier is shown at H, and itor a part thereof is adapted to move in planes or in directions transverse to the line of feed. This movement is preferably an oscillation upon a fixed or movable pivot c. This holder or carrier may consist of an endless belt or chain k, Figs. l and 2, a portion of which runs in an oscillatory guide b, and provided with stave holding or engaging portions a, or it may consist of a reciprocating carriage b', the stave-holder a of which is oscillatory or otherwise freely novable in or on the carriage. In the first instance the stave-holders a are formed by tappets Secured to and carried by the endless chain, While in the second instance, Fig. 4, there is but one such holder a formed by the upturned end of a lever k'. This lever is mounted upon the pivot c, which is mounted in and moves or reciprocates with the carriage b', and consequently renders the holder a freely movable.

The car'ia e b' slides in a suitable "uide or frane and may be reciprocated through a rack z and a pinion (not shown) engaging the same.

In Fig. 1 the chain is double and the tappets are in the form of transverse bars secured to and between the parts of the chain, and the guide b is also double, as clearly seen in Fig. l, and mounted on pivot or hinge c. 4

In Fig. 2 the chain is single, lying directly under the stave, and the tappets are in the form of blocks Secured to the chain and having upwardly-extending parts adapted to engage the rear ends of the staves. In this construction the oscillatory guide is also single, inclosing the chain and forming a slide for the tappets, as seen in Fig. 3.

dis a counterbalancing-weight which tends to support the weight of the holder and stave without interfering with its freedom of movement. This weight may be connected with the .holder a through the medium of a lever p, rod q, and the guide b, as in Figs. 1 and 2, 01' by being Secured to an extension 15 of the the edges, as in Figs. 2, 3, 4, and 5. These lever k', Fig. 4, when the latter `form of the invention is employed. The Weight d may also be applied to an extension of the guides b, as shown in dotted lines in Figs. l and 2.

u indicates the support foithe stave at the point where it is ope'ated on by the eutte's, upon which support it is held by the presse* or clamping plate oiplates 1, which bear against the stave with a yielding p'essure, so as to keep it fi'mly in place without inpeding its feed.

The staVe-holde' is provided with suitable means for engaging the stave, such i as a point a'.

What I claim is- 1. In a machine for planing or jointing staves, the oonbination, with the cutters, of a freely-yielding holder and carrier adapted to engage the stave and movahle t'ansversely to the direction of the feed or longitudinal movement of the stave, substantally as set forth.

2. The combination,with the cutters, of an endless carrier 01' belt provided with means foiengaging the stave, and a freely-yielding guide for the belt, substantially as set forth.
